Original reading
After feeling tired during afternoon lessons, Quang decided to examine his routine rather than buy a product promising instant energy. He noticed that he often stayed up late to finish tasks he had postponed. With help from his family, he moved homework earlier and kept a regular bedtime. He also began walking with a friend after school. They chose a safe route and increased the distance gradually. Quang did not remove entire food groups from his meals; he aimed for variety and drank water regularly. After several weeks, he felt more alert, but he knew his experience was not a medical experiment. He could not prove which change had helped most. When tiredness returned during an illness, he told an adult and sought appropriate medical advice. His class report emphasised realistic habits and asking for help. A healthy routine was something to sustain, not a competition to follow the strictest rules.
